Vapor-liquid equilibrium in binary systems formed by acetonitrile, 2-butanone
Compounds found at elevated levels in whole body tissue samples included acetone, 2-butanone
, benzene, trichloroethane, toluene, ethylbenzene, total xylenes, aluminum, copper, chromium, lead, manganese and silver.
4-ethyl- 3-hydroxy- 2-methyl- 2-methoxy- Pheromone compound: 2-butanone
thiazolidine phenol 3-hydroxy-2-butanone
oxime was purchased from Aladdin Chemistry Co.
The second type was a tin catalyzed sealant (blue) that released noncorrosive 2-butanone
oxime during curing.
(Aldrich) was used as the standard in all tests because it elicited a strong EAG response in other Tephritidae, including Bactrocera tryoni (Hull & Cribb 2001), A.
2011); Dimethyl sulphide, 2-butanone
, ethyl acetate, 2- and 3-methylbutanal, 2-heptanone, dimethyl trisulphide and nonanal were detected as key flavor compounds of cooked Irish Angus beef while methional, 2,4-nonadienal and bezothiazole were known to impart meaty, oily notes in cooked Belgian Blue, Limousin and Aberdeen Angus beefs (Machiel et al.
The scientists found 2-butanone
and hexanal in all of the milk samples during the entire study period.
2] Polar (nonaldehyde) Acetic acid, 2-butanone
, organic carbon Aromatic Benzene, toluene, ethylbenzene, m-xylene and p-xylene, o-xylene, n-propylbenzene, p-ethyltoluene, m-ethyltoluene, 1,3,5-trimethylbenzene, 1,2,4-trimethylbenzene and sec-butylbenzene Aldehyde Benzaldehyde, heptanal, hexanal, octanal Alkane 2,2,4-Trimethylpentane, 2,2-dimethylbutane, 2,3,4-trimethylpentane, 2,3-dimethylbutane.
The ink was left on the film for 16 hr after which a paper tissue wetted with isopropyl alcohol (IPA) or 2-butanone
(MEK) was used to remove the graffiti from the coating surface.
When the enzyme converted the substrate 2-butanone
into 2-butanol at 15 degrees C, it favored the left-handed form, which made up 55 percent of the product.
Tests were conducted for VOCs including hexane, decane, toluene, tetrachloroethylene, 2-butanone
, isobutanol, and D-limonene.
In this case, a file containing the spectra of ozone, benzene, toluene, 2-butanone
(MEK), and ortho-, para-, and meta-xylene was first created by metering known concentrations of each compound in a stream of air flowing through the instrument's absorption cell.
The autoclave was then opened and the reaction mixture was dissolved in 100 mL of 2-butanone
and washed with distilled water (2 X 100 mL), [Na.
